This isn't necessarily an accurate statement, as proved by this output on
my machine:

garyj:peedub:freebsd:-bash:23> sysctl kern.timecounter.hardware
kern.timecounter.hardware: ACPI-fast
garyj:peedub:freebsd:-bash:24> while : ; do date ; sleep 1 ; done

Mon May 29 21:26:38 CEST 2006
Mon May 29 21:26:39 CEST 2006
Mon May 29 21:26:40 CEST 2006
Mon May 29 21:26:41 CEST 2006
Mon May 29 21:26:42 CEST 2006

and so on ad nauseum.

No problem on my machine. Must be something specific to your set up.
